Connect jdbc sqlserver in soapui MockService

When making a connection to the sql server in a MockService using soapui version 5.4 I get the following error:

  

INFO: groovy.lang.MissingPropertyException: No such property:   connectionUrl for class: Script1

The code I have is the following:

import com.eviware.soapui.support.XmlHolder
import groovy.sql.Sql
import java.sql.Driver

def holderDataXml= new XmlHolder(mockRequest.requestContent)
try {
def db = [url:'jdbc:sqlserver://'+ /name1\name2:1433/+ '/Database', user:'user', password:'password']

def sql = Sql.newInstance(db.url, db.user, db.password, "com.microsoft.sqlserver.jdbc.SQLServerDriver")

} catch (Exception e) 
{
    log.info e
    context.ResultResponse = "Invalid Xml"
}

I do not know what can be failing or missing, suddenly an import.
